BACKGROUND OF THE INVENTION

The prior art includes different solutions of traffic signalling devices of pole type in general, and of device of milestone type for signalling of alignments in circulation ways.

It is known to produce this type of devices in synthetic material, including one pole part, for example with a general shape of cylindrical type produced by means of plastic extrusion, and one base part with a general shape of disc type.

One of the problems associated with this type of devices is respective fixation, in simple and ergonomic manner to the pavement, by means of reduced cost and providing a reliable retention.

In particular, the pole part presents an engagement part adapted so that engages in an engagement part configured in corresponding manner on the base part, so that the engagement unfolds by means of a vertical movement.
